KnProxy is a small PHP based Web proxy that makes use of the cURL module built into PHP. It uses limited server resources while still maintaining performance. KnProxy is aimed to be easy to use and does not inject information into Web pages. It returns the Web page as is, only changing the links to the resources to be proxied. The URL is obfuscated to prevent tracking or URL filtering. KnProxy has extended support for AJAX calls and JavaScript. This tool can be useful in places where the Internet is not as free as intended. It is also good for bypassing school or office firewalls. It is especially optimized to get past the GFW of China.

NiX Proxy Script is a Web-based proxy script. It is similar to a typical proxy server; a Web proxy script downloads requested Web pages and files and forwards them back to the user. The service is provided through a Web page, which allows instant access to the proxy without editing your browser connection settings.

KnProxy Lambda is a branch of KnProxy that uses Java and PHP to provide users with a safe and balanced proxy service. Communications between the Java client and the PHP based server are encrypted in highly secure encryption methods. Traffic is also distributed among many servers to prevent flow monitoring. KnProxy Lambda allows users to set up a full proxy processing POST, GET, and AJAX Requests on any server offering PHP. It is also compatable with APJP servers, allowing for a wider network and an easier migration.
